Bronchial artery embolization for prevention of bleeding during bronchoscopy thermal ablation in patients with central lung cancer / 中国介入影像与治疗学

ABSTRACT

Objective: To explore the preventive effect of bronchial artery embolization (BAE) for bleeding during bronchoscopy thermal ablation (BTA) in patients with central lung cancer. Methods: Clinical data of 49 patients with central lung cancer with airway stenosis treated by BTA were retrospectively analyzed. The patients were divided into two groups according to the method of treatment, in Group A (n=25) received only BTA, while in group B (n=24) received BAE before BTA. Then intraoperative bleeding of BTA was compared between 2 groups. Results: Among 25 patients in group A, 16 underwent successful BTA, 9 with mild bleeding in cases, 7 with moderate bleeding, whereas BTA had to be terminated due to massive bleeding in 9 cases. All 24 patients in group B underwent successful BAE, among them 22 underwent completed BTA, 18 with mild and 4 with moderate bleeding, and BTA was terminated in 2 cases due to massive bleeding. The intraoperative bleeding in group B was less than that in group A (P=0.02). Conclusion: BAE before BTA in patients with central lung cancer is safe and feasible, which can significantly reduce the risk of massive bleeding during BTA.
